    Significance and Use

    This procedure serves as a screening process for carbon blacks used in the manufacturing of products that are to come into contact with food. The cyclohexane extract absorbance at 386 nm must be less than 0.10 for a 50 mm cuvette in order to fulfill various regulatory requirements.

    ^SCOPE:

    1.1 This method covers the determination of extinction (absorbance) of carbon black cyclohexane extract at 386 nm using a UV spectrophotometer.

    1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
